How To Set Up WebDAV With Lighttpd On Debian Squeeze

This guide explains how to set up WebDAV with lighttpd on a Debian Squeeze server. WebDAV stands for Web-based Distributed Authoring and Versioning and is a set of extensions to the HTTP protocol that allow users to directly edit files on the lighttpd server so that they do not need to be downloaded/uploaded via FTP. Of course, WebDAV can also be used to upload and download files.

I do not issue any guarantee that this will work for you!

1 Preliminary Note

I'm using a Debian Squeeze server with the IP address 192.168.0.100 here.

2 Installing WebDAV

You can install lighttpd (if it's not already installed), the lighttpd WebDAV module and the apache2-utils package (which contains the tool htpasswd which we will need later on to generate a password file for the WebDAV share) as follows:

apt-get install lighttpd lighttpd-mod-webdav apache2-utils

Afterwards, we must make sure that the directory /var/run/lighttpd is owned by the www-data user and group. This directory will contain an SQLite database needed by WebDAV:

chown www-data:www-data /var/run/lighttpd/

Next, we enable the modules mod_auth and mod_webdav:

lighty-enable-mod auth lighty-enable-mod webdav

Reload lighttpd afterwards:

/etc/init.d/lighttpd force-reload

3 Creating A Virtual Host

I will now create a lighttpd vhost (www.example.com) in the directory /var/www/web1/web. If you already have a vhost for which you'd like to enable WebDAV, you must adjust this tutorial to your situation.

First, we create the directory /var/www/web1/web and make the lighttpd user (www-data) the owner of that directory:

mkdir -p /var/www/web1/web chown www-data:www-data /var/www/web1/web

Then we open /etc/lighttpd/lighttpd.conf and add the following vhost to the end of the file:

The alias.url directive makes (together with $HTTP["url"] =~ "^/webdav($|/)") that when you call /webdav, WebDAV is invoked, but you can still access the whole document root of the vhost. All other URLs of that vhost are still "normal" HTTP.

Restart lighttpd afterwards:

/etc/init.d/lighttpd restart

5 Testing WebDAV

We will now install cadaver, a command-line WebDAV client:

apt-get install cadaver

To test if WebDAV works, type:

cadaver http://www.example.com/webdav/

You should be prompted for a user name. Type in test and then the password for the user test. If all goes well, you should be granted access which means WebDAV is working ok. Type quit to leave the WebDAV shell:
